摘要：
A control unit controls supply of power to a plurality of heating units at predetermined control period T1 that is set by a first unit. A second unit sets power supply time t1 for a first heating unit having largest power consumption within the control period T1 and power supply time t2 for a second heating unit having second largest power consumption. A third unit controls to supply the power to the first heating unit for the power supply time t1 from beginning of the control period T1 and to supply the power to the second heating unit from a point obtained by subtracting the power supply time t2 from end of the control period T1 to the end of the control period T1.
